CRDs

PizzaCustomer

The PizzaCustomer CRD represents a customer who might want to place an order at Dominos.

In its spec, one fills the fields that will let Dominos know of your personal information, address, and a reference to a secret where credit card details can be found.

kind: PizzaCustomer
apiVersion: ops.tips/v1alpha1
spec:
  address: etcetc
  name: bla

The reconciler has the responsability of finding stores nearby the customer so that orders can be placed for it later on.

status:
  conditions:
    - type: Ready
      status: "True"
      reason: StoresFound
  closestStoreRef: { name: store-123 }

So ultimately, it's a state machine like so:

where:

• Ready implies that stores have been found and orders for that customer can be placed
• Errored implies something went wrong

PizzaStore

A PizzaStore object represents a physical Dominos location where one can order food from.

kind: PizzaStore
apiVersion: ops.tips/v1alpha1
spec:
  name: bla
  products:
    - code: 10SCREEN
      name: ""
      description: ""

It's not supposed to be created by humans - PizzaStore objects are created by the controller.

PizzaOrder

With a PizzaOrder object, you declare the intention to have food from a Dominos store by filling three fields:

• spec.storeRef: reference to a PizzaStore object
• spec.customerRef: reference to a PizzaCustomer object
• spec.products: set of products to order from that store

kind: PizzaOrder
apiVersion: ops.tips/v1alpha1
spec:
  storeRef: { name: store-123 }
  customerRef: { name: customer-1 }
  serviceType: carryout
  products:
    - code: 10SCREEN
      quantity: 1
  payment:
    creditCardSecretRef:
      name: credit-card

under the hood, the reconciler is working on the following state machine:
